The new OSSPEED B21 Ongaro V3 Edition is based on the proven B2105 engine and has been equipped with additional features to celebrate Davide Ongaro's third world championship title.
Further developments of the OSSPEED B2105

OSSPEED's off-road racing engine has been further developed. The B2105, now in the fifth generation of the B21 series, has been specifically optimized for demanding off-road racing. It not only offers more power to secure an advantage in challenging racing situations, but also a better driving feel. The changes allow for smoother rotation. Furthermore, the lighter external cooling head ensures improved drivability.

Features of the OSSPEED B2105 Ongaro V3 Edition:

• Cooling head: B2105 cooling head with black and gold double anodizing and "Ongaro V3" laser engraving.
• Crankcase: Special laser engraving with glossy "OS SPEED" and "B21" logo.
• Venturi reducer: 24K gold-plated 6.5 mm reducer (as used by Ongaro at the World Championship).

• Exhaust system: TB02 EFRA2089 (T-2090SC) with "Ongaro Signature & World Champion" engraving and MB01-75 (M2000SC) 75mm header.

!!! Note: None of the V3 Edition parts are available separately. The motor is only available as a combination set.

Technical improvements in detail:

Cooling head
Double anodizing in black and gold according to Ongaro's specifications.
Laser engraving with "V3" logo for an exclusive design.

Venturi reducer
Gold plated (24K), based on the model used by Ongaro during the World Championship.

crankcase
Special engraving and shiny logos on both sides.

Cylinder/piston
The B2105 uses a three-port design. The shape of the ports has been adjusted to improve air-fuel mixture flow, resulting in higher torque.

crankshaft
DLC (Diamond-Like Carbon) coating and a revised inner shape not only improve the performance characteristics but also the rotational stability.

back wall
The B2104's back plate with a specially treated pressure plate reduces wear caused by friction between the connecting rod and the back plate, which extends the service life.

Glow plug: OSSpeed T-P3 Gold.
Venturi: 6.5mm, 24K gold plated.
Sealing ring for exhaust.
Dust cap set: 3, 16 & 18 mm.
